Sodium polyacrylate content

Sodium polyacrylate PAAS is a polymer compound with the molecular formula (C3H3NaO2) n, where n represents the degree of polymerization. Sodium polyacrylate powder or liquid produced by different manufacturers may have differences in formula and production process, so their composition content may also vary.

Generally speaking, the main component content of sodium polyacrylate powder for industrial use is as follows:

Purity: Generally required to be above 90%, high-purity products can provide better performance and more stable quality.

Moisture content: Generally below 10%, high moisture content will affect the stability and effectiveness of the product.

Acidity: Generally between 6 and 8, too low or too high can affect the stability and effectiveness of the product.

Half price: Generally between 30-100 ℃, a high half price means that the product is more easily soluble and dispersed.

Base equivalent: Generally between 400-500mg/g, high base equivalent means that the product is more difficult to hydrolyze, which can improve the stability of the product.

As for the main component content of liquid sodium polyacrylate, common indicators include solid content, pH value, viscosity, etc. The specific content should refer to the product manual and relevant quality inspection reports.
